OCP CBT Question 646

Please solve the following question.

Which of the following describes a key difference between an RMAN image copy and an RMAN backup set?

An image copy is always compressed, while a backup set is never compressed.

An image copy is directly usable by the database without RMAN processing, whereas a backup set requires RMAN to extract data files.

Backup sets can only be stored on tape, while image copies can only be stored on disk.

Image copies support incremental backups, but backup sets do not.
